Question

A car with an initial velocity 45 km/hr increases its speed to 70 km/h in 5 min,find it's acceleration. ​

Answer 1

Explanation:

time = 5 × 60 = 300 sec = 5/60 hour

vi = 12.5 m/s

vf = 19.45 m/s

acceleration = final velocity - initial velocity / time

a = 19.45-12.5/300

= 0.0231m/s^2

or

a = 300 km/hr^2
